AUTOMATIC GAS-VALVE FOR DOWN-SPOU'IS.

Application filed September 29, 1913.

T 0 all whom it may concern Be it known that I, EDWARD GRUENINGER, a citizen of the United States, residing at Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Automatic Gas- Valves for Down-Spouts, of which the following is a specification.

It is the object of my invention to provide a novel automatic gas valve for downspouts, such as down-spouts leading from the roofs of houses into sewer systems.

It has been found in practice that the sewer gases have a corroding effect upon the clown-spouts, and it is the object of my invention to avoid passage of these gases through the down-spouts.

It is the object of my invention further to provide novel means for deflecting the sewer gas into the atmosphere while permitting free passage of the water through the down spout; and, further, to provide novel means whereby the seat of the valve is protected from corrosion.

The invention will be understood from the following description and claims, and from the drawings, in which latter:

Figure 1 is a perspective view of my improved device with a side of the casing partly broken away. Fig. 2 is a plan view of the same. Fig. 3 is a central vertical section of the same on the line 33 of Fig. 2. Fig. 4: is a detail of the valve in section on the line H of Fig. 3. Fig. 5 is a hori zontal section on a line corresponding to the line 55 of Fig. 3. Fig. 6 is a horizontal cross-section on a line corresponding to the line 66 of Fig. 3; and, Fig. 7 is a plan view of the valve.

11 represents the casing of my improved device, which is shown as a casing which tapers downwardly, being preferably straight at one side and slanting at its other side, and provided with rounded end walls and comparatively flat side walls, and formed with a rounded lower end.

12 is an inlet-pipe suitably secured in the top 13 of the casing. This top, adjacent to the inlet-pipe is preferably imperforate, as shown at 14, for protecting the valve parts hereinafter described from the rain, the balance of said top being preferably grated for forming a grated opening, as shown at 15, the grating preventing leaves and other in- Specification of Letters Patent.

terfering objects being introduced into the casing. The down-spout 16 is arranged to be received in the inlet-pipe.

The lower end of the casing is in the form of a collar 21 forming an outlet for the easlng and is received in a suitable drain pipe 22 which has connection with the sewer. The water inlet is shown directly above the water outlet at the straight side of the eas- I provide novel means for preventing corrosive gases from entering the down-spout and inlet-pipe and for easy escape of said gases into the atmosphere.

The lower end ofthe inlet-pipe is formed tapering for forming a downwardly slanting valve-seat 23 with which a valve 24: coacts. This valve is shown as a pipe section, suitably cut for shaping its lower end. tapering, forming a lip 25. The bore 26 of its upper end 27 forms a gas-passage, presented toward the grated opening 15. The valve is so hinged as to normally hang against the valve-seat, as by a hinge comprising a U- further readily shaped bracket 28, secured adjacent to the upper end of the valve and received through eyes 29 secured to the inlet-pipe adjacent to the upper end of the tapering portion of the latter.

The portion of the valve which coacts with the valve-seat is in the form of a lip which tapers downwardly and is crosssectionally rounded .for presenting a bulged downwardly slanting surface 30 to the inlet- 'pipe and a channeled upwardly slanting surface 31 to the outlet opening communicating with the gas-passage 26, so that water descending from the inlet-pip may be readily shed from said valve and gas passing through said outlet opening may be readily directed toward said grated opening.

The parts are so related as to automatically force the valve into coaction with its valve-seat by gravity. Thus the cylindrical portion 27 of the valvepipe forms a counter-weight. The axis of the cylindrical portion, when the valve is closed, is substantially at an acute angle to the axis of the inletpipe. The lip 25 is substantially a continuation of the cylindrical countenweight portion.

For protecting the valve-seat I provide the lip 25 with a peripheral flange 32 arranged to be received below the valve-seat and preferably coacting with the walls of the casing adjacent to said valve-seat for forming a protecting chamber 33 at the said valve-seat, the inlet-pipe and the valve-seat being in said chamber, the said flange slanting slightly downwardly toward its outer edges for forming a gas deflecting surface at its bottom merging into the lower face of the lip. I

In. use, the gases rising in the drain-pipe 22 will strike the gas deflecting lower surface on the flange and the gas deflecting surface 31 on the valve, the said surfaces acting to deflect the said gases through the gas passage 26 and out through the grated opening 15 in the top of the casing. ater passing down the pipe will strike the upper surface of the lip of the valve, being quickly drained past the peripheral flange thereof,

and causing swinging of the valve on its 7 hinge away from the seat 23 on the inletpipe against the action of the counterweight portion 27, the valve immediately swinging back into place.

Havlng thus fully descrlbed my lnvention,

" whatI claim as new and desire to secure by Letters Patent, is:

1. In an automatic gas valve for downspouts, the combination of a casing, an inletpipe arranged in said casing, said inlet-pipe having a downwardly tapering lower end which forms a valve-seat, and a valve in said casing for said valve-seat having a downwardly tapering lip provided with a transversely bulging downwardly sloping water deflecting upper surface coacting with said valve-seat and a transversely channeled downwardly sloping gas deflecting lower surface, said valve being counterweighted for normally urging said lip toward said valve-seat.

2. In an automatic gas valve for downconnection and formed as a grated opening at the other end of said cover, and thebore v of said valve-pipe opening upwardly below said grated opening, substantially as de- 7 scribed.

3. In a device of the character described,

the combination of a case, an inlet-pipe provided with a valve-seat within said case, and a valve-pipe pivoted within said case to said inlet-pipe and arranged to contact said seat, said valve-pipe provided with a flange arranged to coact with the walls of said case for forming a protective chamber within said case above said flange for protecting said valve-seat on said inlet-pipe, said valvepipe having an upper end opening upwardly above said seat, and said case provided with a grated opening above said upper end of said valve-pipe, substantially for the purpose set forth. v

In testimony whereof, I havehereunto signed my name in the presence of two subscribing witnesses.
